Using a DataOutputStream/DataInputStream method multiple times for writing and reading to/from a stream in Java

Question

How do I use a particular method from the DataOutputStream/DataOutputStream classes multiple times to write to an OutputStream and read the datas from the InputStream

Sender Side:

String directory = ...;
String hostDomain = ...;
int port = ...;

File[] files = new File(directory).listFiles();

Socket socket = new Socket(InetAddress.getByName(hostDomain), port);

BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream());
DataOutputStream dos = new DataOutputStream(bos);

dos.writeInt(files.length);

for(File file : files)
{
    long length = file.length();
    dos.writeLong(length);

    String name = file.getName();
    dos.writeUTF(name);

String type = file.getType();
dos.writeUTF(type);

    FileInputStream fis = new FileInputStream(file);
    BufferedInputStream bis = new BufferedInputStream(fis);

    int theByte = 0;
    while((theByte = bis.read()) != -1) bos.write(theByte);

    bis.close();
}

dos.close();

Receiver Side:

String dirPath = ...;

ServerSocket serverSocket = ...;
Socket socket = serverSocket.accept();

BufferedInputStream bis = new BufferedInputStream(socket.getInputStream());
DataInputStream dis = new DataInputStream(bis);

int filesCount = dis.readInt();
File[] files = new File[filesCount];

for(int i = 0; i < filesCount; i++)
{
    long fileLength = dis.readLong();
    String fileName = dis.readUTF();
String fileType = dis.readUTF();

    files[i] = new File(dirPath + "/" + fileName);

    FileOutputStream fos = new FileOutputStream(files[i]);
    BufferedOutputStream bos = new BufferedOutputStream(fos);

    for(int j = 0; j < fileLength; j++) bos.write(bis.read());

    bos.close();
}

dis.close();

In the Sender Side, I've used dos.writeUTF(name) and dos.writeUTF(type) ,and used the dis.readUTF() which are twice in receiving side. But,there don't seem to be a way of distinguishing which of the Strings is being read with the readUTF() methods in the receiving side. Are the Strings read in the sequence they're sent? I'll like that my code be updated ,if incorrect,to help me achieve my objective.
